Fixing an issue that caused DEVPORT to always be set.


Without a bool string present, using "# CONFIG_DEVPORT is not set" in
defconfig files would not actually unset devport. This ensured that
/dev/port was always on, but there are reasons a user may wish to
disable it (smaller kernel, attack surface reduction) if it's not being
used. Adding a message here in order to make this user visible.

Say Y here if you want to support the /dev/port device. The
/dev/port device is similar to /dev/mem, but for I/O ports.
